Thanks for taking the time to leave this feedback!
As far as the enemy chasing the player endlessly, I've definitely seen some odd interactions around this. I'll have them check for closer targets occasionally.
Making the potions clickable is a great idea. It's also fairly trivial to add so I'm about to do that now.
I'll see if I can move the full screen button in the itch.io settings.
As for healing, I had a healing potion for a while that I ought to add back in. I also thought about having enemies drop healing items, or allowing players to exchange reagents for healing at shrines.
I like the suggestions and am working on interactions like lightening stunning and doing more damage when on an enemy standing over water.
Thanks again for the feedback, really appreciate it!
Update: I updated the game with your button suggestion and made the enemies check for new (closer) targets occasionally.
